From the related PR[^1] in `devenv`:
Injecting `LD_LIBRARY_PATH` to the Python runtime environment is great
to bypass the need of having to patch non-nix binaries loaded into
that environment, however it breaks down, when Python executes any
other program not compiled for the given Nix system, e.g. a shell
script via `subprocess`.
To work this around, `devenv` will inject a `pth`[^2] file to the virtual
environment it creates, which mangles the `LD_LIBRARY_PATH` variable,
undoing any changes to it made by `devenv` but preserving changes from
other sources.
